I have a 94 faststrike 150 that for no reason or warning will just stall . I checked to see if it was firing and it was not . All 6 cylinders had no fire. Local shop installed new power pack & optic sensor. Still stalls , sometimes it won't fire on a cold start up and then it will just start and may run fine for a whole week end. <br /> Secondly, I am considering installing Boyesen reeds and I was wondering what will be involved in doing this ? Re-jetting, Timing,etc... Also can any one tell me the factory intermediate air bleed orfice size & idle air bleed orfice size ?<br /><br /> Thanks <br /> Tom
